Porting WIFI SoftAP in Android 6.0

[petertseng]

Hi i.MX Community,

I try to porting WIFI modules BCM43241 to our i.MX6 custom board.

I can normally use WIFI to connect to the Internet.

But the following error occurs when I start SoftAp.

Hope for your help!

Can you erase or rename the following directory?:

"/data/misc/wifi"

and then try it again?

[petertseng]

I try to delete the "/data/misc/wifi" directory and then reboot to startup SoftAP.

But the result is still the same.

[SergioSolis]

Did you make sure the directory was deleted after rebooting?, are you using a GA bsp or a user debug?

[petertseng · Accepted solution]

Yes, I sure.

I found this patch will cause the 'hostapd' service could not start.

Some people come across the same problem?
